Description: Field of the Invention . This invention relates to an automobile sunvisor structured on a hollow body formed by blow or injection moulding of a plastics material. Background of the Invention Automobile sunvisors manufactured from a hollow body formed by blow moulding a plastics material, such as, among others, polypropylene and polythene, are well known and widely produced industrially. As a known embodiment of such sunvisors, there may be cited Spanish patent P 9100391 (corresponding to EP-A-0 525 148) which discloses a sunvisor in which the said hollow body comprises a fixing spring for receiving the pivot pin of the support attached to the vehicle structure, so that the sunvisor may be rotated about such pivot pin and the support itself, a hanging bridge, which may engage a corresponding support, also attached to said structure, an external sheath-like covering formed by a sheet of thin plastics material, conferring on the sunvisor an external finish in accordance with the finish of the vehicle passenger compartment, and any additional device such as may be the so-called vanity mirror which is normally included as original equipment in the passenger side sunvisor. Further to the foregoing, the sunvisor hollow body according to Spanish patent P 9100391 (corresponding to EP-A-0 525 148) is completely filled with a plastics material acting as structural reinforcement and avoiding, under normal conditions of use, the deformation of the sunvisor. A further known embodiment of said sunvisors is the one disclosed in Spanish patent P 9102450 (corresponding to EP-A-0 562 085 published on 29.09.93) which describes a sunvisor comprising the above mentioned functional members, i.e., a fixing spring, a hanging bridge, an external sheath-like covering and the said additional device. In this case, i.e. in the sunvisor of Spanish patent P 9102450 (corresponding to EP-A-0 562 085), the structural reinforcement of the hollow body is achieved with a plurality of ribs disposed (on the inside of the larger facing sides. The structural reinforcing members described above included in the hollow bodies of the sunvisors of Spanish patents P 9100391 (corresponding to EP-A-0 525 148) and P 9102450 (corresponding to EP-A-0 562 085) confer on said sunvisors a high degree of rigidity which gives the user a feeling of excessive hardness when handling such sunvisors and which in certain cases may mean that the finish of such sunvisors is clearly not in keeping with the interior finish of the vehicle passenger compartment when it is furnished with top quality equipment and accessories. The usual sheath or external covering does not provide a satisfactory reduction of said feeling of excessive hardness. It is known from the patent document GB-A-2 204 290 to dispose a layer of foamed P.V.C. or polyuretane between the body of the visor and a P.V.C. cover. But this layer is merely adapted on the external surface of the assembled modular parts forming the body of the visor. Brief Summary of the Invention To provide a solution to the above problem, caused by the feeling of hardness perceived by the user when handling the known embodiments of sunvisor such as those described above, a new embodiment of automobile sunvisor is disclosed. The sunvisor of the invention comprises a hollow body formed by blow or injection moulding of a plastics material, preferably a polyolefin such as polypropylene, having an essentially rectangular prismatic shape, the profile of which is variable in accordance with the configuration of the automobile passenger compartment. The sunvisor of the invention comprises, furthermore, the known members described below. A fixing spring arranged in the inside of the hollow body and dimensioned to receive the corresponding pivot pin of a bent support attached to the vehicle structure and having means which, when the sunvisor is attached to said support, enables the sunvisor to be rotated by the user about said pivot pin and to occupy stable positions of use and the rest position(s) of the sunvisor to be set. A hanging bridge which, suitably disposed relative to the fixing spring, may engage a corresponding support also attached to the vehicle structure. Once the hanging bridge is engaged with the said support, it provides the sunvisor with an additional point of support for relieving possible mechanical overloads on the coupling of the pivot pin of the bent support with the fixing spring. An additional device, such as may be the so-called vanity mirror which is normally included as original equipment in the passenger side sunvisor. Structural reinforcing means which, arranged in the inside of the hollow body, prevents the sunvisor from being deformed under normal conditions of use. And an external sheath-like covering made from a plastics material, preferably polypropylene, providing the sunvisor with a surface finish in keeping with the interior finish of the automobile passenger compartment. The sunvisor of the invention is characterized in that on one or both of the larger sides of the hollow body there is a respective recess of substantially constant depth, the length and contour of which are variable depending on the dimensions and shape of said hollow body. The recess forms the housing for the sheet of soft spongy material prepared preferably from foamed polyolefin. Said sheet of soft spongy material is so dimensioned in length and thickness snugly to be housed in said recess, flush with the corresponding outer surface of the hollow body. The sheet is comprised between the hollow body itself and the external covering, wherewith the latter is provided defining a corresponding soft area. In accordance with a further characteristic embodiment of the sunvisor of the invention, it comprises the known members described above and is characterized by a recess of substantially constant depth, the length and contour of which are variable depending on the dimensions and shape of the hollow body, said recess forming a housing for the sheet of soft spongy material, preferably made from foamed polyolefin. Said sheet of soft spongy material is so dimensioned in length and thickness snugly to be housed in said recess flush with the outer surface of said hollow body. The sheet is comprised between the hollow body itself and the external sheath-like covering, wherewith the latter is provided defining a soft area extending around the lower longitudinal edge of the sunvisor, between both larger sides of the sunvisor. The above described features of the sunvisor of the invention provide a low cost solution for the problems occasionally arising from the hard feeling presented by the known embodiments of sunvisors such as those described. In fact, in both characteristic embodiments of the sunvisor of the invention, the recess or recesses in the hollow body and the corresponding sheets of soft spongy material housed in said recesses are dimensioned in correspondence with the dimensions and shape of the sunvisor and occupy the portions of the larger sides of the sunvisor which are taken hold of by the user, under normal conditions of use, to change the position of the sunvisor. In this way, when the user takes hold of the sunvisor, he presses on the soft areas, thereby avoiding the said feeling of hardness. Furthermore, the fact that the sheet of soft spongy material is flush with the corresponding outer surface of the hollow body and between it and the external covering or sheath implies that in no way is the outer appearance of the sunvisor affected in any way, whereby said outer covering of the hollow body suffers no detriment in retaining the function of making the external finish of the sunvisor appropriate to the finish of the vehicle passenger compartment. Brief Description of the Drawings The automobile sunvisor of the invention is illustrated in the sheets of drawings of the specification. In the drawings: Figure 1 is a front view showing one embodiment VP1 of the sunvisor of the invention. Figure 2 is a cross-section view on the line II-II of Figure 1. Figure 3 is a cross-section view on the line III-III of Figure 1. Figure 4 is a front view showing an embodiment VP2 of the sunvisor of the invention. Figure 5 is a cross-section view on the line V-V of Figure IV. Detailed Description of the Embodiment Both embodiments VP1 and VP2 of the automobile sunvisor of the invention described as examples of embodiments have the same constructional members which, for greater clarity, are designated in the specification and drawings with the same references. In this way, the following description of said constructional members relates to the sunvisor embodiment VP1 shown in Figures 1, 2 and 3 and, by extension, it is fully applicable to the exemplified embodiment of the sunvisor VP2 shown in Figures 4 and 5. Figures 1, 2 and 3 of the drawings show how the sunvisor embodiment VP1 of the invention comprises the following known members: the hollow body 1; the fixing spring 2; the holding bridge 3; the external covering 4; and the structural reinforcing means RE disposed in the hollow body 1. These known members are described below. The hollow body 1 is produced by blow moulding polypropylene which, as is known, is a completely recyclable material, i.e., it may be reused industrially once the working life of the sunvisor has ended. The figures show how the hollow body 1 is of an essentially prismatic rectangular shape, the contour or perimeter of which is adapted to a particular configuration of the vehicle passenger compartment. The dimensions and contour of the hollow body 1 will obviously be determined in each particular application by the configuration of the said passenger compartment, whereby the hollow body 1 shown in said Figures 1, 2 and 3 is given only as an orientative example. The fixing spring 2 is made from highly resilient sheet steel and is essentially an elongate prismatic rectangle symmetrical about its centre line. As shown in Figures 1 and 2, the fixing spring 2 is arranged inside one of the ends of the hollow body 1 and is framed by the recesses 5, the number and distribution of which suitably set the position of the fixing spring 2 in the inside thereof. The longitudinal recesses 6 and 6' of the fixing spring 2 define the upper longitudinal cavity 7, shown in Figure 2, for snugly receiving the pivot pin 8 of the bent support 9 shown in Figure 1 which, as said above, is fixed to the vehicle structure. When the sunvisor has been attached to the bent support 9, through the fixing spring 2 and the pivot pin 8, respectively, the sunvisor may be rotated around the pivot pin 8 and occupy stable positions of use, the rest position of the sunvisor being fixed by way of the positioning flats 10- 10' and 11 on the fixing spring 2 and pivot pin 8 of the bent support 9, respectively, to be seen in Figures 1 and 2. The hanging bridge 3, shown in Figure 1, is situated at the end of the hollow body 1 opposite to the end occupied by the fixing spring 2 and is suitably disposed relative to the latter. The hanging bridge 3, defined by the opening 12 formed for this purpose in the hollow body 1, is dimensioned in correspondence with a support which, for greater clarity, has not been shown in said Figure 1 and which is attached to the vehicle structure. Once the sunvisor is attached at the respective ends thereof to the bent support 9 and to said not shown support, the latter engagement, i.e., the engagement of the hanging bridge 3 with the support, is for relieving mechanical overloads on the joint formed by the fixing spring 2 and by the pivot pin 8 of the sunvisor and of the bent support 9, respectively. The structural reinforcing means RE consists, as shown in Figures 2 and 3, of the reinforcing ribs 13- 13' which are arranged symmetrically on both larger inner sides 14- 14' , respectively, of the hollow body 1. Such reinforcing ribs 13- 13' are essentially frustoconical in shape and bear upon each other at their respective facing edges, whereby the mechanical capacity to withstand deformation under normal conditions of use of the hollow body 1 is substantially increased in this way. The above described items of the embodiment of the sunvisor VP1 of the invention are conventional. Figures 1, 2 and 3 show how the larger outer sides 15- 15' of the hollow body 1 are provided with respective, essentially rectangular recesses 16- 16' which are approximately coextensive with the hollow body 1 and half as wide. The longitudinal recesses 16- 16' are dimensioned and situated in those portions of the hollow body 1 of the sunvisor which are normally taken hold of by the user to change the position of the sunvisor. Therefore, both longitudinal recesses 16- 16' shown in Figures 1, 2 and 3 are given only as a guidance since, the dimensions and location of such longitudinal recesses 16- 16' will obviously depend on the needs of each particular application and, to be precise, will be defined by the dimensions and shape of the sunvisor hollow body. The recesses 16- 16' are of a relatively shallow, uniform depth and define a housing which is completely filled by respective soft spongy sheets 17- 17' , made preferably from foamed polypropylene which, like the material used for manufacturing the hollow body 1, is an industrially recyclable material. The soft spongy sheets 17- 17' are die cut and are dimensioned to just the same size as the longitudinal recesses 16- 16' containing them. In this way, Figures 2 and 3 show how the soft spongy sheets 17- 17' are arranged flush with the respective larger sides 15- 15' , respectively, of the hollow body 1, i.e., they do not project from their respective housings formed by the longitudinal recesses 16- 16' . The external covering, or sheath, 4, shown in part in Figures 1, 2 and 3, completely covers the outer surface of the hollow body 1 and, like the hollow body 1 and the soft spongy sheets 17- 17' , it is preferably made of polypropylene. The external covering 4, apart from conferring a surface finish on the hollow body 1 in keeping with the finish of the vehicle passenger compartment, is superimposed on the hollow body 1 in such a way that neither the holes 18- 18' , produced when forming the reinforcing ribs 13- 13' inside of the hollow body 1, nor the perimetral edges 19- 19' of the longitudinal recesses 16- 16' , respectively, may be felt. Figures 2 and 3 show how the soft spongy sheets 17- 17' are arranged between the larger outer sides 15- 15' , respectively, of the hollow body 1 and the outer covering 4, consequently defining respective soft areas M - M' on the respective larger outer sides of the sunvisor. These soft areas M - M' , as said above, are arranged precisely in those areas of the sunvisor which are normally taken hold of by the user to change the position of the sunvisor. In this embodiment of the sunvisor VP1 of the invention, there are contemplated two soft areas, one for each larger outer side of the sunvisor. This is obviously not a limitation of the invention, since a single soft area may be contemplated on one side or the other of the sunvisor. Thus, whether one or the other of these options is adopted, i.e. the presence of one or two soft areas in the sunvisor, one for each of the larger sides, will depend only on the requirements of each particular application. On the other hand, the sunvisor embodiment VP1 of the invention as described above relates to a sunvisor not having any additional device such as may be the so-.called vanity mirror or any other device increasing the functionality of the sunvisor. It should be understood that if said sunvisor VP1 were to include one of such additional devices, this would in no way affect the essence of the invention, since it would obviously only affect the dimensions of the longitudinal recess and of the respective soft spongy sheet provided on the corresponding side of the sunvisor which, in this case, would have a contour similar to that of the sunvisor and to that of the device incorporated therein. Figures 4 and 5 show an embodiment VP2 of the sunvisor of the invention which, as said above, comprises the same known elements described for the sunvisor embodiment VP1 of the invention. Figures 4 and 5 show how the two larger sides 15 and 15' of the hollow body 1 are bridged at their lower longitudinal edge which, as shown in Figure 4, is the longitudinal edge opposite to the one where the fixing spring 2 is located by a recess 20 of substantially constant depth. This recess 20 is approximately coextensive with the hollow body 1 and is dimensioned in such a way as to occupy the areas normally taken hold of by the user to change the sunvisor VP2 position. In a similar way as for the previously described embodiment of sunvisor VP1 , the dimensions and shape of the recess 20 shown in Figures 4 and 5 are given only as a guidance, since said recess 20 may have any other dimensions depending on the needs of each particular application, without this affecting the essence of the invention. The recess 20 defines a corresponding housing occupied by the soft spongy material 21 produced by diecutting and preferably made from polypropylene. The dimensions of the soft spongy sheet 21 snugly mate with the dimensions of the recess 20 so that, as shown in Figure 5, it is flush with the corresponding surfaces of the hollow body 1 of the sunvisor VP2 , i.e. flush with the larger sides 15 and 15' and with the lower longitudinal edge joining them. The outer covering 4, shown in part in Figures 4 and 5, covers the whole of the outer surface of the hollow body 1 and is superimposed thereon so that neither the holes 18- 18' produced during the forming of the reinforcing ribs 13- 13' , nor the perimetral edge 22 of the recess 20 can be felt. Figure 5 shows how the soft spongy sheet 21 is arranged between the bottom of the recess 20 and the outer covering 4, thereby defining a soft area M2 which, extending continuously around the lower longitudinal edge, bridges both larger sides of the sunvisor VP2 of the invention. Said soft area M2 precisely occupies those portions of the sunvisor VP2 normally taken hold of by the user to change its position. Also in a similar way as has been described for the sunvisor embodiment VP1 of the invention, in this sunvisor embodiment VP2 shown in Figures 4 and 5, no additional device such as may be, among others, the vanity mirror has been contemplated. It will obviously be understood that if the sunvisor VP2 were to comprise one of such additional devices, this would not affect the essence of the invention, since the presence of such device would simply involve the dimensions of the recess 20 of the hollow body 1 and of the corresponding soft spongy sheet 21, in both cases in the portion comprised on the corresponding larger face of the sunvisor VP2 on which such additional device was disposed.
